2. SCOPE OF WORK 2. Transportation / Circulation Issues The proposed 56 single-family houses on the site could substantially alter existing traffic volumes and patterns in the site vicinity. The effect of increased traffic on Lake Chabot Road and on circulation within the project site would be of special importance. It is understood that the Lake Chabot Terrace EIR was prepared for a larger development proposal at the project site. ESA will review the Traffic and Circulation section of that EIR and will make maximum use of relevant information contained therein as part of our analysis of the current proposal. It is our judgment, however, that the age of the existing traffic count data (1987-90 timeframe) suggests that new count data will need to be collected. Tasks • Consult with the City of San Leandro to agree on the details of the analytic approach and assumptions, including the identification of study intersections. Review existing data and studies performed for the area, including the Lake Chabot Terrace EIR (analysis prepared in 1990 for a previously proposed 134-home development) for appropriateness and to determine additional data needs. • Conduct a.m. and p.m. peak -hour traffic turning movement counts at up to seven intersections. Note: This proposal assumes that new peak -hour traffic data for the selected study intersections will need to be collected. To the extent that current traffic data are available, the effort associated with this task will be reduced. • Calculate existing level of service at the selected intersections using methodologies in the Highway Capacity Manual. • Conduct traffic signal warrant analyses for unsignalized intersections. Calculate levels of service under signalized conditions for any intersections for which existing traffic volumes satisfy the signal warrants. • Describe the existing roadway network and traffic conditions in the vicinity of the site, using existing data and field reconnaissance. , • Establish significance criteria that will be used to judge project and cumulative impacts. • Forecast trip generation and trip distribution associated with the proposed plan and with cumulative development in the project vicinity. The EIR cumulative analysis will rely on data, including previous traffic analyses, compiled by the City and made available to ESA. Boulders Residential Development EIR 13 of 37
